So I've been playing for a while and almost every time this utility vehicle thing appears at four badges. It has a great top speed and acceleration. It's four wheel drive, yet one of the best drifters in the game. My problem is I can't find any way of buying one (car dealer or pawn shop), it sells for $32,500 at the chop shop. Does anybody know if I can purchase this thing anywhere?
